Abstract: A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

Abstract: Methods and systems are provided for the circulation of blood using a purge-free miniature pump. In one embodiment, a pump is provided that may comprise a housing including a rotor and a stator within a drive unit. In this embodiment, the pump may establish a primary blood flow through the space between the drive unit and the housing and a secondary blood flow between the rotor and stator. In another embodiment, a pump establishes a primary blood flow outside the housing and a secondary blood flow between the rotor and stator. In yet another embodiment, a method is provided for introducing the pump into the body and circulating blood using the pump.

Abstract: An integrated sheath assembly for inserting a medical device such as a percutaneous pump into a vessel can include a first sheath having a first lumen defining a first opening between proximal and distal ends of the first sheath for passage of a portion of the pump and a second sheath having a second lumen defining a second opening between proximal and distal ends of the second sheath. The second lumen is expandable to allow passage of the first sheath containing the portion of the pump. The first sheath fills a space between the second sheath and the portion of the percutaneous pump when the first sheath containing the percutaneous pump is inserted into the second lumen. The first sheath has a first hub, and the second sheath has a second hub. In some embodiments, a single sheath and a movable connector can be integrated on the medical device.
